## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to exercise strollers and more particularly pertains to a new exercise stroller for exercising the arms and a portion of an upper torso of a user.
2. Description of the Prior Art
The use of exercise strollers is known in the prior art. U.S. Pat. No. 6,196,947 describes a system for using arm movement of a user during jogging to propel a stroller. Another type of exercise stroller is U.S. Pat. No. 5,876,309 having a stroller that allows a user to move their arms in a more natural motion when jogging with the stroller. Another type of exercise stroller is U.S. Pat. No. 5,674,165 having a device that is coupled to a stroller to allow the arms of user to move in a more natural motion when jogging with the stroller.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that has certain improved features such as a crankshaft that allows for the entire motion of the users arms to propel the stroller across a surface while using the weight of the stroller to provide resistance to the arms of the user to work the arms of the user during extension and retraction.
SUMMARY OF THE INVENTION
The present invention meets the needs presented above by generally comprising a seat to receive and support a rider. A frame is coupled to the seat to support the seat in an elevated position above a ground surface. A plurality of wheels is coupled to the frame and engages the ground surface. Each of the wheels rolls across the ground surface when the frame and the seat are being moved. A crankshaft is rotatably coupled to the frame and releasably engages a pair of the wheels. The crankshaft rotates the associated pair of the wheels to propel the frame and the seat across the ground surface when the crankshaft is rotated with respect to the frame and the crankshaft is engaged with the associated pair of the wheels. A pair of handle assemblies are operationally coupled to the crankshaft and pivotally coupled to the frame. One of the handle assemblies pivots in a direction opposite the other one of the handle assemblies in a substantially scissor like motion to rotate the crankshaft with respect to the frame.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 9 thereof, a new exercise stroller embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 9, the stroller apparatus 10 generally comprises a seat 12 to receive and support a rider. A frame 14 is coupled to the seat 12 to support the seat 12 in an elevated position above a ground surface. A plurality of wheels 16 is coupled to the frame 14 and engages the ground surface. Each of the wheels 16 rolls across the ground surface when the frame 14 and the seat 12 are being moved.
A crankshaft 18 is rotatably coupled to the frame 14 and is releasably engaged to a pair of the wheels 16. The crankshaft 18 rotates the associated pair of the wheels 16 to propel the frame 14 and the seat 12 across the ground surface when the crankshaft 18 is rotated with respect to the frame 14 and the crankshaft 18 is engaged with the associated pair of the wheels 16. A hub assembly 20 is coupled to one of a pair of opposing ends 22 of the crankshaft 18. The hub assembly 20 is actuated to a first position to engage the crankshaft 18 to one of the associated pair of the wheels 16 when the crankshaft 18 is to be used to rotate the one of the associated pair of the wheels 16 or to a second position to disengage the crankshaft 18 from the one of the associated pair of the wheels 16 when the wheels 16 are to rotate independently of the crankshaft 18. The hub assembly 20 is preferably threadably coupled to the crankshaft 18 and may be moved to the first position by tightening the hub on the crankshaft 18 and thereby secure the wheel 16 to the crankshaft 18.
A pair of handle assemblies 24 is operationally coupled to the crankshaft 18 and pivotally coupled to the frame 14. One of the handle assemblies 24 pivots in a direction opposite the other one of the handle assemblies 24 in a substantially scissor like motion to rotate the crankshaft 18 with respect to the frame 14. Additionally, the scissor like motion of the handle assemblies 24 causes the arms of the user to be extended away from and retracted to the torso of the user to exercise the arms, shoulders and a portion of the torso of the user. Each of the handle assemblies 24 comprises an actuating arm 26 pivotally coupled to the frame 14. The actuating arm 26 pivots with respect to the frame 14 when the actuating arm 26 is pushed and pulled by a user. A length of the actuating arm 26 extending upwardly from the frame 14 is adjustable. A translation rod 28 is telescopically coupled to the actuating arm 26. A distal end 30 of the translation rod 28 with respect to the actuating arm 26 moves in a pendulum motion when the translation rod 28 telescopes from the actuating arm 26 and the actuating arm 26 is pivoted with respect to the frame 14. A linking arm 32 is rotatably coupled to one of a pair of crankpins 34 of the crankshaft 18 and rotatably coupled to the distal end 30 of the translation rod 28. The linking arm 32 converts pendulum motion of the translation arm into circular motion transferred to the associated one of the crankpins 34 of the crankshaft 18 to rotate the crankshaft 18.
A locking arm 36 is pivotally coupled to one of the handle assemblies 24 and is selectively extendable into a deployed position extending between the handle assemblies 24 and engaging the actuating arm 26 of the other of the handle assemblies 24 to inhibit pivoting of one of the handle assemblies 24 with respect to the other one of the handle assemblies 24. A latch pin 38 is coupled to the locking arm 36 to facilitate rotation of the locking arm 36 between the deployed position and the stored position.
In use, the hub assembly 20 is actuated to the first position to engage the crankshaft 18 to the associated one of the wheels 16. The user then grips the actuating arm 26 of each of the handle assemblies 24 and by pushing and pulling the handle assemblies 24 through the scissor like motion actuates the crankshaft 18 to rotate the associated one of the wheels 16 and thereby propels the frame 14 and seat 12 across the surface. When the user pushes and pulls the handle assemblies 24 the user works the arms, shoulders and a portion of the upper torso to propel the frame 14 and seat 12 across the surface. When the hub assembly 20 is actuated into the second position to disengaged the associated one of the wheels 16 from the crankshaft 18 and the locking arm 36 engages both handle assemblies 24, the wheels 16 roll freely from the crankshaft 18 thereby allowing the frame 14 and seat 12 to be moved freely across the surface without having to actuate the handle assemblies 24 in the scissor like motion.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
